Description

A kind of impeller and axial flow blower

Technical field

The utility model relates to air-conditioning, ventilation and refrigeration technology fields, in particular to a kind of impeller and axis stream wind Machine.

Background technique

One wheel hub and multiple blades constitute impeller, and the air duct that impeller, motor and spiral case are formed collectively constitutes wind Machine.Blower is broadly divided into axial flow blower, cross flow fan and three kinds of centrifugal blower with the difference of gas flow direction.Wherein, leaf Wheel due to it is lasting rotation and directly receiving wind pressure, belong to the critical component of blower.

Impeller on the market at present, including without shield solar or lunar halo and have shield two kinds of structures of solar or lunar halo.Shield solar or lunar halo is inscribed in each blade Outer rim, each blade is linked together, the non-deformability of blade is effectively enhanced.

By taking axial flow blower as an example, its working principle is that air inlet through hollow shaft, the axial outlet air after the effect of the pressure of blade.Axis stream The blade of blower is by center hub radial radiation around, at work due to the effect by air pressure, it is easy to deform. Fig. 1 is the structural schematic diagram in the prior art without shield solar or lunar halo impeller.As shown in Figure 1, in the blower without shield solar or lunar halo structure, Blade 4 and wheel hub 1 must be designed enough to solid, thick and heavy enough, and this undoubtedly increases the material cost and driving electricity of blower The power consumption of machine.

Fig. 2 is the structural schematic diagram in the prior art for having shield solar or lunar halo impeller.As shown in Fig. 2, having shield in the prior art The blower of solar or lunar halo structure can effectively reduce the thickness of each blade 4, reach although joined shield this design element of solar or lunar halo Mitigate the purpose of 4 weight of blade, and improves its non-deformability, but also just due to being provided with shield solar or lunar halo, to increase entire The weight of impeller, so that mitigating weight, the final effect of reduction energy consumption is not obvious.

So how to improve the structure design of the even entire blower of impeller, loss of weight level is improved, material cost is reduced, changes The effective use of kind power of motor is those skilled in the art's urgent problem to be solved.
